The outer surfaces of the cup member, with the exception of the portion 24 may be silvered or otherwise coated with a substance to produce a mirror surface, as at 26. p

In the operation of assembling the lamp the rim portion 16 is forced out as'shownin Fig; 3 andthe cup member inserted thecasing; the flexibility of the casing in the non-secured relaflange I I whereupon therinr Cupmember 2| and thereby snugly retaining the parts in assembled relation, without the use of spring means such as are iusuallyfemployed in lamp structuresto prevent looseness and rattling Ofpartsh,

In Figs. 5 and 6 I have iiustratee a tmodified form of the invention adapted to a head-light lamp, In this form thecasing fl is of bulletor' other suitable shape and is provided at its forward edge with an inturned flange 23. 'A strut member 29 is 'insertedand securedwithin the casing and constitutes a support' for-the lamp socket'member 30, as well as anabutmen't for the glass insert member 3| which-is provided with a central opening 32 surrounding the socket memberr'3fl, The glass cupmembeiinthis case Q is of parabolic shape,'exc ept for the forward end ing screw engages, as, Wilbpresently more fully a for surfacdas at 34;

at' 35, extendingfor a portion which is shapedjto conform to theinner slightly outwardly diverging surface of the casing.

A cut-out 33 is provided in'the'f orward 'edge of the cup member in which'the end of the securappear, and the v outer surface of the' mp mem: her is silvered or otherwise provided with a mir Q The casing is ,provi substantially I distance rearwardly from the rim]! I, so that the forwardiportion of the casing may be readily spread open topermit the insertion of; the cupmember and the glass lens 36,' which lens, as 'in 'the form of the invention shown inFigs. 1',to 4, has its outer edge portion ,wedged'between the forward edge of the cup member andthe flange 28. A securing lip member 31 is attached to the casing at one sideof the-slit 35, as by'spot-welding or other suitable means, and'overlaps the casing at the other side of the slit, where it is provided with a set screw 38' which engages a threaded hole in the casing to thereby secure the parts in as-,

sembled relation. 1 3 i Y I have illustrated and described preferred and satisfactory embodiments of -the invention, but it, will be obvious that changes may be made therein, within the spirit; and scope, thereof as,
